DETAILED DESCRIPTION

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. It is apparent that the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

In S11, a random-access request is received from an unmanned aerial vehicle, where the random-access request includes a preamble.

In S12, in a case that the preamble is as same as a preset preamble, it is determined that the unmanned aerial vehicle is equipped with a dedicated chip for a cellular network unmanned aerial vehicle, and the unmanned aerial vehicle is managed in an unmanned aerial management manner.

In S13, in a case that the preamble is different from the preset preamble, it is determined that the unmanned aerial vehicle is equipped with a terminal and establishes a communication connection through the terminal, and the unmanned aerial vehicle is managed in a terminal management manner.

In an embodiment, a preamble dedicated to a random-access procedure may be set in advance for an unmanned aerial vehicle which is equipped with a dedicated chip for a cellular network unmanned aerial vehicle, and the preamble is as same as a preset preamble stored in a base station. The unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle may transmit, during the random-access procedure, a random-access request carrying the preamble.

An unmanned aerial vehicle which is equipped with a terminal (e.g., a mobile device such as a mobile phone) can transmit a random-access request to the base station through the terminal and the random-access request also includes a preamble, but the preamble is not a dedicated preamble, so the preamble is different from the preset preamble stored in the base station.

The base station may extract, after receiving the random-access request, the preamble in the random-access request, and determine whether the preamble extracted is as same as the preset preamble. If the preamble is as same as the preset preamble, it may be determined that the unmanned aerial vehicle transmitting the random-access request is an unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle, and the unmanned aerial vehicle may be managed in an unmanned aerial vehicle management manner. If the preamble is different from the preset preamble, it may be determined that the unmanned aerial vehicle transmitting the random-access request is an unmanned aerial vehicle which is equipped with the terminal and which transmits the random-access request through the terminal, and the unmanned aerial vehicle may be managed in a terminal management manner.

Based on this, it is possible to accurately distinguish the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle from the unmanned aerial vehicle which is equipped with the terminal and which establishes the communication connection through the terminal. Further, the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle is managed in the unmanned aerial vehicle management manner, and the unmanned aerial vehicle which is equipped with the terminal and which establishes the communication connection through the terminal is managed in the terminal management manner, so that the unmanned aerial vehicle which is equipped with the terminal and which establishes the communication connection through the terminal is prevented from interfering with the cellular network corresponding to the base station.

FIG. 2 is a flowchart of another method for managing an unmanned aerial vehicle according to an exemplary embodiment. As illustrated in FIG. 2, the unmanned aerial vehicle is managed in the unmanned aerial vehicle management manner includes the following operation.

In S121, communication with the unmanned aerial vehicle is performed on at least one of: a dedicated time domain resource, a dedicated frequency domain resource, or a dedicated space domain resource.

In an embodiment, at least one of a dedicated time domain resource, a dedicated frequency domain resource, or a dedicated space domain resource may be allocated for the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle. Here, the dedicated time domain resource is different from a time domain resource used for communication between the base station and the terminal, and the dedicated frequency domain resource is different from a frequency domain resource used for communication between the base station and the terminal, thereby ensuring that the base station may communicate well with the unmanned aerial vehicle. The dedicated space domain resource includes a space domain resource that avoid a route of a flight, so as to avoid impact of the communication with the unmanned aerial vehicle on the flight, or impact of communication of the flight on the communication of the unmanned aerial vehicle.

FIG. 3 is a flowchart of yet another method for managing an unmanned aerial vehicle according to an exemplary embodiment. As illustrated in FIG. 3, the unmanned aerial vehicle is managed in the unmanned aerial vehicle management manner includes the following operation.

In S122, responsive to detecting that communication with the unmanned aerial vehicle interferes with another device, signal strength of the communication with the unmanned aerial vehicle is reduced.

In an embodiment, when it is detected that communication with the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle interferes with another device (for example, since the unmanned aerial vehicle flies at higher altitudes and there are fewer objects capable of blocking signal transmission, the unmanned aerial vehicle may receive signals from more base stations and may establish a communication connection with a more distant base station across a closer base station, so that a signal transmitted from the more distant base station to the unmanned aerial vehicle may pass through the closer base station, which affects a device in communication with the closer base station), in this case, according to the terminal management manner, the communication connection may be directly disconnected; according to the unmanned aerial vehicle management manner, the signal strength of the communication with the unmanned aerial vehicle can be reduced, thereby ensuring that the communication with the unmanned aerial vehicle can still be performed, and the impact of this communication process on other devices is alleviated.

FIG. 4 is a flowchart of still another method for managing an unmanned aerial vehicle according to an exemplary embodiment. As illustrated in FIG. 4, in a case that the preamble is different from the preset preamble, the method further includes the following operations.

In S14, identification information of the unmanned aerial vehicle is recorded.

In S15, the identification information of the unmanned aerial vehicle is transmitted to another base station.

In an embodiment, if the preamble is different from the preset preamble, it may be determined that the unmanned aerial vehicle transmitting the random-access request is an unmanned aerial vehicle which is equipped with the terminal and which transmits the random-access request through the terminal. The unmanned aerial vehicle needs to be managed in the terminal management manner. For example, the unmanned aerial vehicle is managed as a common mobile phone.

In this case, identification information of the unmanned aerial vehicle may be recorded. Since the random-access request includes the identification information of the unmanned aerial vehicle transmitting the random-access request, the identification information is transmitted to another base station, so that upon reception of the random-access request by the another base station from the unmanned aerial vehicle, the another base station can determine, according to the identification information of the unmanned aerial vehicle, that the unmanned aerial vehicle is an unmanned aerial vehicle which is equipped with the terminal and which transmits the random-access request through the terminal, without performing a comparison on the preamble in the random-access request. Thus, a base station which does not store the preset preamble in advance can quickly and accurately determine that the unmanned aerial vehicle is an unmanned aerial vehicle which is equipped with the terminal and which transmits the random-access request through the terminal, and then manages the unmanned aerial vehicle in the terminal management manner.

FIG. 5 is a flowchart of yet still another method for managing an unmanned aerial vehicle according to an exemplary embodiment. As illustrated in FIG. 5, in a case that the preamble is as same as the preset preamble, the method further includes the following operations.

In S16, identification information of the unmanned aerial vehicle is recorded.

In S17, the identification information of the unmanned aerial vehicle is transmitted to another base station.

In an embodiment, if the preamble is as same as the preset preamble, it may be determined that the unmanned aerial vehicle transmitting the random-access request is an unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle, and the unmanned aerial vehicle is managed in the unmanned aerial vehicle management manner.

In this case, identification information of the unmanned aerial vehicle may be recorded. Since the random-access request includes the identification information of the unmanned aerial vehicle transmitting the random-access request, the identification information is transmitted to another base station, so that upon reception of the random-access request by the another base station from the unmanned aerial vehicle, the another base station can determine, according to the identification information of the unmanned aerial vehicle, that the unmanned aerial vehicle is an unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle, without performing a comparison on the preamble in the random-access request. Thus, a base station which does not store the preset preamble in advance can quickly and accurately determine that the unmanned aerial vehicle is an unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle, and then manages the unmanned aerial vehicle in the unmanned aerial vehicle management manner.

In S62, connection establishment acknowledgment information, which is transmitted by the base station according to the preamble, is received to establish the communication connection with the base station.

In an embodiment, the preamble dedicated to the random-access procedure of the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle is preset in the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle. During the random-access procedure to the base station, the dedicated preamble may be added into the random-access request transmitted to the base station, so that the base station can determine, according to the dedicated preamble, that the unmanned aerial vehicle transmitting the random-access request is the unmanned aerial vehicle which equipped with the dedicated chip for the cellular network unmanned aerial vehicle. Further, after the communication connection is established, the unmanned aerial vehicle can be managed in an unmanned aerial vehicle management manner.

FIG. 7 is a flowchart of another method for establishing a communication connection according to an exemplary embodiment. As illustrated in FIG. 7, before the random-access request is transmitted to the base station, the method further includes the following operations.

In S63, multiple preambles dedicated to random-access procedures of the unmanned aerial vehicle which is equipped with the dedicated chip for the cellular network unmanned aerial vehicle are set according to a received setting instruction.

In an embodiment, multiple preambles dedicated to the random-access procedures of the unmanned aerial vehicle which is equipped with the dedicated chip for cellular network unmanned aerial vehicle may be preset for the unmanned aerial vehicle equipped with the dedicated chip for the cellular network unmanned aerial vehicle for storage, so that the unmanned aerial vehicle can transmits random-access requests to different base stations according to different preambles.
